High-speed I/O jitter modeling methodologies

As data rate pushes to 10Gbps and beyond, timing jitter has become one of the major factors that limit the link performance. Thorough understanding of the link jitter characteristics and accurate modeling of their impact on link performance is a must even at early design stage. This paper discusses the characteristics of timing jitter in typical I/O interfaces and overviews various jitter modeling methods proposed in the literature during the past few years. Recommendations are given based on the characteristics of timing jitter and their locations.
